If your JSP files are also under src/web and you're using paths 
relative to that, or the URIs in the TLD files themselves, it should 
already be finding them.  Otherwise the 
.settings/org.eclipse.wst.common.component needs a addition like 
<wb-resource deploy-path="/" source-path="/src/web"/> and your 
project needs the org.eclipse.wst.common.modulecore.ModuleCoreNature 
nature on it.

But then, if this is a Java project meant to be built through Maven, 
they provide some sort of WTP project support for you.
